Last night on the nation’s center of right wing propaganda, Fox News, Sarah Palin casually overstated the cost of the Libya intervention — by 700%.

Pentagon figures show that the Libyan operation cost about $600 million in the first seven days, but Palin told her pal Greta Van Susteren (and millions of Fox viewers who will now repeat it endlessly like robot parrots) that it cost that much every day.

PALIN: And that’s the $600 million dollar-a-day question that is being asked now because that’s the cost incurred by Americans as we support the no-fly zone, which, of course, the no-fly zone, the intervention or enactment is turning into more than that.

Is Palin really so dim that she didn’t understand the Pentagon’s figures — or was she deliberately lying because she knew her audience would swallow her false claim without blinking?
